I own two pairs of 512's in the same size. One pair fits me exceptionally well, and the other I received is considerably smaller in every dimension. This smaller pair was initially okay with me as I don't mind close fitted pants on occasion, but after I washed and dried them I went from having just enough extra space in them to not being able to wear them anymore because they are too tight on my ankles and thighs; they fit much like a 510 super skinny jean. Maybe I should have known better and returned them, but I digress.
The other pair I have are longer and leave more space for my thighs, calves, and waist and this is after many washes.
This inconsistency extends beyond the 512's. Every styles of Levis jeans I have vary considerably in all dimensions by and inch or more.
